Usage

command line	Description
./jvmw jvm_wrapper_commands or ~/.jvm/jvmw jvm_wrapper_commands	Execute the internal JVM Wrapper commands. This does not check and update the JVM
./jvmw java arguments or ~/.jvm/jvmw java arguments	Running JVM commands. In this case, the computed JVM Wrapper path is used as the path. Currently, only the java and javac commands are supported
./jvmw command arguments or ~/.jvm/jvmw command arguments ./jvmw ./command arguments or ~/.jvm/jvmw ./command arguments	Running external commands

Instead of java or javac, you can use any command from $JAVA_HOME/bin/

JVM Wrapper Commands

command	description
info or empty	Prints information about paths to JDK_HOME, JAVA_HOME
upgrade	Update JVM Wrapper with GitHub. Updating the running script (self-update)

Properties

Order of reading variables: environment, ~/jvmw.properties, ./jvmw.properties. The last read value is set for the variable

jvmw.properties

property name	default	examples	description
JVM_VERSION	11	see examples of configuration files
JVM_VENDOR	openjdk	oracle, openjdk	openjdk = OpenJDK oracle = Oracle Site
JVMW_ORACLE_KEYCHAIN	JVM_WRAPPER_ORACLE	Specifies the name of the Keychain Item, which stores the login (ORACLE_USER) and password (ORACLE_PASSWORD)
ORACLE_USER		ORACLE_USER=[email protected]
ORACLE_PASSWORD		ORACLE_PASSWORD=password	Value in the clear. It is recommended to use Keychain. If the parameter is not specified and the parameter JVMW_ORACLE_KEYCHAIN is not specified, an attempt will be made to find the password in Keychain by the parameter ORACLE_USER
JVMW_DEBUG	N	Y, N	If JVMW_DEBUG=Y, debugging information will be displayed in stderr
REQUIRED_UPDATE	Y	Y, N	If REQUIRED_UPDATE=N, then an attempt will not be made to load the JDK / JVM distributor. If the required version of JDK/JVM is not found locally, an error will be generated If REQUIRED_UPDATE=Y and the required version is not locally found, an attempt will be made to download the distribution from the Oracle website
USE_SYSTEM_JVM	N	Y, N	If the requested version of JDK is present in the system, then it will be used. If you want to explicitly specify that the system JDK is not used, you must specify USE_SYSTEM_JVM=N
CLEAR_COOKIE	Y	Y, N	Delete authorization cookies after script completion. Set Y if the script runs several times in a row, so as not to re-authorize on the vendor site

Properties are read without replacing the previously read. For example, if environment does not have an empty JVM_VERSION variable and also has ./jvmw.properties, then the variable from the environment

To download archival versions of JDK, you must set the variables ORACLE_USER and ORACLE_PASSWORD
